This is the King of Games Starman T-Shirt, but this particular one is really rare and was only given out in small numbers at the MOTHER 1+2 event. Most people just know it as the shirt Itoi wore during the event, though. More info here.

I can’t remember the exact interview(s), but I’m pretty sure that Miyamoto said at one point that he only watched the projects from afar and didn’t do much with them himself.

VERY quickly, the messages say:

* Thank you for coming today. Please continue enjoying the games forever and ever.

* Please enjoy the games through time/beyond time/well into the future

* I’ve never really been sure whether or not Mother should be part of the list of my creations, alongside things like Mario and Zelda. The Mother series is Mr. Itoi’s creation, and they are very memorable games to me.

(These are very rough so don’t quote them fully. Someone with more time, feel free to do better translations!)
